Montgomery County Fire and Rescue units were dispatched to Frederick Rd (355) at King Farm Blvd at approximately 5pm.
The collision between what looks to be two vehicles led to an overturned vehicle with at least one person trapped inside.
Rescue units were able to extricate occupant(s) and three adults are currently being evaluated for non-life threatening injuries. Two were transported to the hospital.
Delays are expected as the road will be closed for a period of time until cleaned up is complete and the vehicle can be towed.
